<h4><a name = "tag_002_001_593">&nbsp;</a>NAME</h4><blockquote>
redrawwin, wredrawln - line update status functions
</blockquote><h4><a name = "tag_002_001_594">&nbsp;</a>SYNOPSIS</h4><blockquote>
<pre><code>

#include &lt;<a href="curses.h.html">curses.h</a>&gt;

int redrawwin(WINDOW *<i>win</i>);

int wredrawln(WINDOW *<i>win</i>, int <i>beg_line</i>, int <i>num_lines</i>);
</code>
</pre>
</blockquote><h4><a name = "tag_002_001_595">&nbsp;</a>DESCRIPTION</h4><blockquote>
The
<i>redrawwin()</i>
and
<i>wredrawln()</i>
functions inform the implementation that some or all of the information
physically displayed for the specified window may have been corrupted.  The
<i>redrawwin()</i>
function marks the entire window;
<i>wredrawln()</i>
marks only <i>num_lines</i> lines starting at line number <i>beg_line</i>.  The
functions prevent the next refresh operation on that window from
performing any optimisation based on assumptions about what is physically
displayed there.
</blockquote><h4><a name = "tag_002_001_596">&nbsp;</a>RETURN VALUE</h4><blockquote>
Upon successful completion, these functions return OK.
Otherwise they return ERR.
</blockquote><h4><a name = "tag_002_001_597">&nbsp;</a>ERRORS</h4><blockquote>
No errors are defined.
</blockquote><h4><a name = "tag_002_001_598">&nbsp;</a>APPLICATION USAGE</h4><blockquote>
The
<i>redrawwin()</i>
and
<i>wredrawln()</i>
functions could be used in a text editor to implement a command that redraws
some or all of the screen.
</blockquote><h4><a name = "tag_002_001_599">&nbsp;</a>SEE ALSO</h4><blockquote>
